The Nomad is a true two-fer in terms of concepts. The original Nomad
that Chevrolet produced between 1955-57 was such a powerful design that
it has spawned numerous concepts, two recently.

The 1999 version is built on fourth-generation Camaro/Firebird
mechanicals. Reminiscent of previous Camaro and Firebird "wagons," the
Nomad features a practical tailgate, generous cargo room, and
performance an SUV can only dream of. Looked at from the front, more
than a hint of first-generation Corvette puts a pure Chevrolet face on
the car.

Timing for this Nomad couldn’t have been worse, as rumors of the Gen IV
F-Bodies (Camaro/Firebird) death were all but confirmed. At the 1999
Detroit Auto Show where the car debuted, the car was virtually ignored
by GM’s PR staff who didn’t want to give the concept too much play as
its chance for production was zero.
